So I been having this problem where my phone will stop vibrating. When I'm typing something the phone will stop vibrating and when I receive a txt it wont vibrate. It will do that for a while and then it will start working again until I start typing again. I don't know whats the problem, it works fine for a couple of minutes then it stops vibrating. Even when I turn off my phone, it still dont vibrate. Does anyone have this issue?
